How to Make Weetabix Cake

Create the Flax Egg: Combine flax seeds and water, allowing them to thicken for approximately 7 minutes.

Prepare Wet Ingredients: In a large bowl, measure and add the Weetbix, raisins, mixed spice, liquid sweetener, and salt. Then add the milk last. Stir to ensure even mixing.

Preheat the Oven: Set your oven to 180℃.

Add Flour and Baking Powder: Add the whole wheat flour and baking powder, mixing until the dough is evenly combined.

Bake: Transfer the mixture to a lined loaf tin and bake for 1 hour.

Top Tips

Measure Ingredients Accurately: Use measuring cups/spoons or, better yet, a kitchen scale. Especially important for baking recipes!
Follow the Order: Add wet ingredients in the right sequence for even and easier mixing.
Thicken the Flax Egg: Let it sit at least 7 minutes until the consistency is slightly thinner than egg whites.

Jazzing Up this Weetabix Cake Loaf

Want some variations for this? Try one of these:

Use cranberries (or any of your favourite dried fruits) instead of raisins.
Add a banana to the recipe to make Weetabix banana bread.
- Be sure to reduce the liquid in this recipe, so start by adding 120 ml (1/2 cup) of milk first. Then check if the consistency is alright (the same as the picture in the How to Make section above). If you need more liquid, then slowly add more milk, 1-2 Tablespoons at a time.
Add some shredded carrots and ginger to make some Weetabix carrot cake
Add some cocoa powder, or use chocolate milk to make Weetabix chocolate cake! Yums!

Storage Instructions

Storage: Keep in the fridge for up to 5 days in an airtight container.

Meal prep: Bake ahead, slice, and store for quick breakfasts or snacks.

Freezing: Freezes well for up to 3 months. Pre-slice so you can defrost individual pieces. Thaw overnight in the fridge, then warm in the oven at 180℃ (5–7 mins thawed, 8–10 mins frozen). A microwave works too, though the texture won’t be as even.

FAQ

Yes, you can! The only caveat is that you need to reduce the liquid used since banana contains some moisture already.

For this, start by adding 120 ml (1/2 cup) of milk first. Then check if the consistency is alright (the same as the picture in the How to Make section above). If you need more liquid, then slowly add more milk, 1-2 Tablespoons at a time.
